Office location

Heyday's headquarters are in the Sophia Antipolis region of France.  Sophia Antipolis is a technopole rich in innovative business and technology.  Our headquarters houses our office and development laboratory in the heart of Grasse city nestled in the French Riviera only 15 minutes from Cannes and the beach and 30 minutes from Nice airport.

Why Heyday?

I first met Heyday at PCIM. What I immediately liked, was the fact that Joe (the CEO) was super accessible and that you could feel how passionate he is about the technology. During the interviews, I met the other colleagues, and I love the fact they were all very friendly and shared the same high level of passion for the future of Heyday.  

Sr IC Engineer

The work is fun, interesting and we explore new frontiers.  We are encouraged to come with bold ideas to explore new avenues. The location is superb. After work I love going to the beach in summer and skiing in the winter!


IC design manager

It's super exciting to work for a company that has great products and the right tools and the right dynamic culture to do enable growth.  Building the bridge between our tech department and clients to create a long-term win-win relationship is what drives me forward.
